LTC1647-3CGN#TRPBF

Hot Swap Controllers Overview

The LTC1647-3CGN#TRPBF is a dual-channel hot-swap controller manufactured by Analog Devices Inc. It operates within an input voltage range of 2.7 V to 16.5 V and supports up to two channels with programmable current limiting. The device utilizes an SSOP-16 surface-mount package and functions across a commercial temperature range of 0°C to +70°C. Key electrical characteristics include a typical operating supply current of 1 mA and integrated power-fail detection capabilities for system protection.

Hot Swap Controllers Feature Summary

• Dual-channel architecture for independent load management
• Programmable current limiting for precise overcurrent protection
• Integrated power-fail detection circuitry
• Soft-start control to minimize inrush current

Hot Swap Controllers Applications

• Hot-swap insertion in backplane systems
• PCI/PCI-X peripheral card interfaces
• Industrial I/O module replacement
• Telecommunications equipment board swapping

Hot Swap Controllers Procurement Notes

Verify the specific suffix against official documentation, as packaging variations may exist. Confirm availability status directly with authorized distributors, as stock levels fluctuate. Ensure the SSOP-16 footprint matches your PCB design constraints. Validate thermal performance requirements against the specified commercial temperature range before finalizing procurement decisions.

Hot Swap Controllers Selection Notes

Select this component when designing systems requiring safe insertion and removal of live circuits. The dual-channel configuration suits applications needing independent control over multiple loads. Consider the 16.5 V maximum input rating for compatibility with standard industrial voltage rails. Evaluate the need for programmable current limits versus fixed-limit alternatives based on specific fault tolerance requirements.
